changes are of sufficient magnitude to originate such large 

 fluctuations in the terrestrial atmosphere, they ought to be 

 capable of direct measurement by instrumental means at no 

 very distant date. 



In stepping from the earth to the sun, to look for the origin of 

 the changes in the air around us, the domain of World 

 Meteorology is extended by about 96,000,000 of miles. 



The meteorologist of the twentieth century must no longer 

 limit his vision to the height of the most elevated cirrus cloud, 

 but, like the astronomer, must keep in touch with all the 

 manifold changes which are for ever taking place in the 

 incandescent envelope of our central luminary. 



O glittering host ! O golden line ! 



I would I had an angel's ken, 

 Your deepest secrets to divine, 



And read your mysteries to men.
